Pushbutton switch device |
摘要 |
A pushbutton switch device has a flat carrier having first and second switch contacts and a switch button arrangement for actuation of the first and second switch contacts. In order that the first and second switch contacts are switched in succession, the switch contacts to be actuated by a switch knob of the switch button arrangement are placed next to one another on the flat carrier. An insert having first and second switching surface parts corresponding to the first and second switch contacts respectively, is placed between the switch knob and the first and second switch contact. Upon initial actuation of the switch knob, the insert closes the first switch contact. Upon continued actuation of the switch knob, the insert will close the second switch contact.
