Abstract: A push button switch comprises a contact rocker member which remains in its actuated position until it is pivoted back into its first position when the actuating push button is actuated again. The actuating button is mounted on the housing and carries a control member which, in the actuated position of the button, co-operates with a latching arrangement on the housing to lock the button to the housing against a return force applied by a tension spring. When the button is actuated again, the control member is released from the latching arrangement on the housing, whereby the switch is automatically switched off.
