The switch module is particularly intended for digital circuits on printed boards and consists of a plastics housing with stationary contact(s) and a pivotally mounted contact strip. The latter is held in one switching position by a tension spring and swung over into a second switching position by a pressure of swivelling actuating key onto the spring. The tension spring simultaneously stresses the swivelling bearing of the key and provides the key resetting force. Preferably the contact spring consists of a M-shaped wire bracket whose side shanks are bent inside or outside. The tension spring engages the centre of the M and pulls the latter to the current supply contact bearings. The contact bearing has two terminals forming a direct current bridge.
