A body member has an opening formed therein. A receiving contact is located in the opening of the body member and has an electrical lead connected thereto which extends out of the body member. The receiving contact has a cavity with an opening at one end which faces the plunger end of the body member. An interior contact is located in the cavity of the receiving contact and is electrically insulated therefrom. An electrical lead is connected to the interior contact and extends out of the body member. A moveable plunger including a plunger contact is located in the opening of the plunger end of the body member. The plunger contact has an opening which releasably supports a shuttle contact at a position spaced away from the interior contact. In this position an electrical connection is provided between the receiving contact lead and the plunger contact by way of the receiving contact and the shuttle contact. Silicone grease is located around the shuttle contact and the plunger contact and in the opening of the plunger contact behind the shuttle contact. An explosive force on the other side of the plunger forces it toward the receiving contact until it is stopped causing the silicone grease to force the shuttle contact from the plunger contact into engagement with the interior contact and the interior wall of the receiving contact to form an electrical connection between the two leads.
