Abstract
A sealed, pushbutton, single pole, normally closed switch for soldering to a printed circuit board. The switch operates by pushing an actuator that compresses a spring and breaks continuity between two terminals by moving a spring contact, disposed in the head of the actuator, away from the terminals. An O-ring is provided in an annular groove around a shaft of the actuator for sealing the switch between the actuator and a cover without significantly changing the actuator force, and the bottom of the switch has an epoxy seal. The method of assembling the sealed switch components is simple and low cost.
