SB-051 Type
This biased push-button switch is typically incorporated in gas cooking appliances, where it is located behind the control panel fitted over the gas tap.
Type 051 is designed to work with the tap family CAL 20703, manufactured by Copreci.
This biased single-pole switch is used in appliances (e.g. gas cookers between the knob and the gas tap), where small currents at 250V AC and high ambient temperatures are frequently operated (i.e. spark ignition). Usually supplied connected in a chain of flexible non-rewirable cables. A variable number of switches can be interconnected in parallel with one or both wires in common, in series, etc. Directly operated (or indirectly, via a custom-designed spring). Wiring, and if requested, the spring, are custom designed. The switch itself is standard and marked with various international conformity marks.
