Abstract

A miniature mechanical switch wherein an elongated tubular housing has a depressible pushbutton at one end and several terminals for connection to a control panel or the like at the other end. The housing confines a fixed contact and a pivotable second contact which is moved into engagement with the fixed contact in response to depression of the pushbutton through the medium of a restoring spring and a bell crank lever which is further biased by a resilient element to move the second contact away from the fixed contact in response to relaxation of pressure upon the pushbutton or in response to renewed depression of the pushbutton, depending upon whether the switch is a so-called momentary switch or a latching switch. The pivots for the lever and for the second contact are defined by a common carrier which forms part of a conductor connecting one of the terminals with the second contact. The fixed contact is connected with another terminal, and two additional terminals are connected with the socket for a light emitting diode located between the pushbutton and the pivot for the second contact. All of the conductors are substantially parallel to the axis of the housing.
