Abstract (en)
[origin: WO9422153A1] Switching devices with contact components secured on a contact support in a device component housing, may have means for monitoring contact burning. According to the invention, the contact support (10, 11, 12) is sub-divided and the contact components (20) are slotted at the rear and fitted on the sub-divided contact support (11, 12). This makes it possible to detect the oscillation behaviour of the contract support as a measure of the burning of the contact components (20).
