An apparatus includes an instrument body and transmission assembly. The instrument body includes a motor, a switch, and an energy source (e.g., an ultrasonic transducer). The transmission assembly includes an end effector, a transmission feature (e.g., an acoustic waveguide), and a switch engagement feature. The end effector includes an active feature (e.g., a harmonic blade) in communication with the energy source. The switch engagement feature is operable to mechanically couple the energy source with the transmission feature in response to the switch engagement feature triggering the switch. A yoke of the instrument body is configured to selectively engage a translating member of the transmission assembly. A release switch is operable to selectively disengage the yoke from the translating member.

1. An apparatus comprising: (a) an instrument body, comprising: (i) a motor, and(ii) a switch in communication with the motor;(b) an ultrasonic transducer; and(c) a transmission assembly comprising an acoustic waveguide, wherein the transmission assembly is configured to selectively engage the instrument body, wherein the transmission assembly is further configured to trigger the switch, wherein the motor is operable to couple the ultrasonic transducer with the acoustic waveguide in response to the transmission assembly triggering the switch. 2. The apparatus of claim 1, wherein the switch is movable between three positions based on movement of the transmission assembly relative to the instrument body. 3. The apparatus of claim 2, wherein the switch is operable to rotate the motor in a first direction when the switch is in a first position, wherein the switch is operable to rotate the motor in a second direction when the switch is in a second position, wherein the switch is operable to place a drive circuit of the motor in an open configuration when the switch is in a third position. 4. The apparatus of claim 3, wherein the motor is operable to secure the ultrasonic transducer with the acoustic waveguide when the motor is rotated in the first direction, wherein the motor is operable to decouple the ultrasonic transducer from the acoustic waveguide when the motor is rotated in the second direction. 5. The apparatus of claim 3, wherein the switch comprises a pivoting member, wherein the transmission assembly comprises an engagement feature operable to contact the pivoting member to change the position of the switch based on longitudinal movement of the transmission assembly. 6. The apparatus of claim 5, wherein the engagement feature comprises a flange. 7. The apparatus of claim 5, wherein the pivoting member has a tear drop shape. 8. The apparatus of claim 1, wherein the instrument body further comprises a yoke, wherein the transmission assembly further comprises a translating member, wherein the yoke is operable to drive the translating member in a longitudinal direction. 9. The apparatus of claim 8, wherein the yoke comprises a U-shaped cavity having a ramp. 10. The apparatus of claim 8, further comprising a spring operable to bias the yoke into engagement with the translating member. 11. The apparatus of claim 8, further comprising a release switch operable to selectively disengage the yoke from the translating member. 12. The apparatus of claim 8, wherein the transmission assembly includes an end effector, wherein the end effector comprises a pivoting arm, wherein the translating member is operable to drive the pivoting arm. 13. The apparatus of claim 1, wherein the instrument body comprises a handle configured to be gripped by a hand of a user. 14. The apparatus of claim 1, further comprising a power source within the instrument body, wherein the power source is operable to power the motor. 15. The apparatus of claim 1, wherein the at least a portion of the instrument body comprises the transducer. 16. An apparatus comprising: (a) an instrument body, comprising: (i) a motor, and(ii) a switch in communication with the motor;(b) an ultrasonic transducer; and(c) a transmission assembly comprising an acoustic waveguide, wherein the transmission assembly is configured to selectively couple with the instrument body when the transmission assembly is received by the instrument body, wherein the transmission assembly is further configured to trigger the switch when the instrument body receives the transmission assembly, wherein the motor is operable to couple the ultrasonic transducer with the acoustic waveguide in response to the transmission assembly triggering the switch. 17. The apparatus of claim 16, wherein the switch is movable between three positions based on movement of the transmission assembly relative to the instrument body. 18. The apparatus of claim 17, wherein the switch is operable to rotate the motor in a first direction when the switch is in a first position, wherein the switch is operable to rotate the motor in a second direction when the switch is in a second position, wherein the switch is operable to place a drive circuit of the motor in an open configuration when the switch is in a third position. 19. The apparatus of claim 18, wherein the motor is operable to secure the ultrasonic transducer with the acoustic waveguide when the motor is rotated in the first direction, wherein the motor is operable to decouple the ultrasonic transducer from the acoustic waveguide when the motor is rotated in the second direction.
