A pogo stick includes (a) a housing, (b) a member movable within the housing, (c) a spring retained at opposite ends by the housing and the member and compressible upon the actuation of the member to a support surface (e.g. ground) and expansible upon the movement of the member from the support surface, (d) a handle on the housing near the housing top and (e) a foot rest on the housing near the housing bottom. A switch normally in an open relationship is operative (a) to a closed relationship upon the actuation of the member to the support surface and (b) to an open relationship upon a movement of the member from the support surface. The switch includes a resilient electrically conductive element and a stationary electrically conductive element normally defining an open relationship. The resilient member is movable in response to the member actuation to the support surface to engage the stationary element and to provide a switch operation in the closed relationship. The resilient element extends beyond a supporting stud for pivotable movement relative to the stud and the stationary element to engage the stationary element upon the member actuation to the support surface. An indicator responsive to the switch operation provides an indication (e.g. distinctive sound) after each particular number of switch operations. The switch and the indicator are disposed within a casing supported by the housing. A reset within the casing is connected to the counter to initialize the count when manually operated.
