<p>A pushbutton for latching and momentary contact functions that is used to actuate contact elements includes a hollow cylindrical housing and a switch plunger displaceable in a lengthwise direction and non-rotatably guided in the housing. An open ring element is rotatably supported on the switch plunger. A spring and stop device for enabling a resting position of the pushbutton is provided. The housing includes an approximately heart-shaped latching guideway for the latching function disposed at an inside wall of the housing. The housing also includes a longitudinal groove for the momentary-contact function and disposed at the inside wall of the housing approximately parallel to the latching guideway and to an actuating direction. Also provided is a guide pin capable of being repositioned between the latching guideway and the longitudinal groove using a tool through an access opening defined by the housing. The guide pin projects radially outward from the open ring element.</p> |
