A reversible electric switch has movable contacts on opposite ends of a rotor adapted for interengagement with diametrically disposed pairs of stationary contacts. Intermittency or rocking of the movable contacts with respect to the stationary contacts is eliminated by extending drive pins from the rotor into the slot provided within the contact face of the movable contact, such pins passing only partially through the thickness of such contact face. Accordingly, the force applied to the movable contacts to achieve rotation thereof is substantially at the interface between the stationary and movable contacts, substantially eliminating any force couple or moment thus precluding any rocking of the movable contact upon the rotor or other relative movement between the two.

Reversible electrical switch

A low voltage DC one-shot circuit momentarily increases the voltage applied by a NiCad battery pack to the gate of a MOSFET. A charge pump generates a supply voltage to a monostable multivibrator which is manually actuated by a switch to emit an output pulse of fixed amplitude and pulse width. The pulse is passed through a level shift network where it is summed with a bias voltage for application to the gate of the MOSFET.
