Abstract
The sealed toggle action switch comprises an operating lever having a front operating arm projecting out of the front component of the casing. The lever has a rear arm, projecting into the casing and carrying a contactor plate for relative sliding and swinging movement. A coil spring is received around the rear arm and is compressed between the contactor plate and the front sealing flange of a soft resilient sealing boot, such sealing flange being compressed against the operating lever. The boot has a rear, outwardly projecting sealing flange which is retained between the front and rear casing components. The contactor plate has a pair of J-shaped flanges which are slidably engageable with first and second fixed contacts having forwardly projecting protuberances, affording a detent action with the J-shaped flanges. In one position of the operating lever, the J-shaped flanges of the contactor plate engage both of the first and second contacts. In the second position of the operating lever, one of the J-shaped flanges is held out of engagement with the second contact by a pair of insulating ramps on the rear casing component. The first fixed contact preferably comprises a contact plate having forwardly projecting contact flanges affording protuberances or humps, over which one of the J-shaped flanges is movable when the contactor plate is moved between its first and second positions. In one position of the operating lever, the front operating arm is adapted to retain the end fitting of a safety lanyard. In this position, the front arm engages tabs which assist in retaining the end fitting of the lanyard.
