A key module (110) for a keyboard is presented. The key module (110) comprises a key tappet (220). The key tappet (220) comprises a coupling portion (322) for coupling with a keycap for the key module (110). The key tappet (220) comprises at least one guiding portion (326, 328) for guiding a translational actuation movement of the key tappet (220) between a rest position and an actuated position. The key tappet (220) comprises at least one tappet stop (324) for limiting the actuation movement. The key module (110) also comprises a trigger element (350) for triggering a switch signal of the key module (110) in response to the actuation movement. The trigger element (350) is attachable to the key tappet (220). The key module (110) further comprises a module housing (230), wherein the module housing (230) is integrally formed. The module housing (230) comprises at least one positioning protrusion (334) for positioning the key module (110) and a circuit substrate of the keyboard. The module housing (230) is formed to movably accommodate the key tappet (220), in order to enable the actuation movement of the key tappet (220) relative to the module housing (230). The module housing (230) comprises at least one housing stop (332) for abutment against the at least one tappet stop (324) of the key tappet (220) in the rest position of the key tappet (220). Moreover, the key module (110) comprises elastic means (340). The elastic means (340) is configured to bias the key tappet (220) into the rest position in an assembled state of the key module (110).

The invention relates to an electric switch that serves to switch on and/or off electric devices and for this purpose has a contact system in the switch housing. By means of a manual actuating element or a remotely controlled actuator, a switching operation can be effected.

An electromagnetic relay includes a fixed spring, a fixed contact configured to be swaged so as to be attached to the fixed spring, a movable spring, and a movable contact provided on the movable spring so as to be capable of making contact with the fixed contact, wherein a swaged portion of the fixed contact is formed so as not to protrude from a surface of the fixed spring.
