Mechanical switching contact

A mechanical switch comprising:

• an insulating support;
• a first pair of mutually spaced contacts fixed on one side of said support and a second pair of mutually spaced contacts fixed on another side of said support opposite the contacts of said first pair;
• a contact carrier rotatably mounted on said support and having two free ends, an electrically conducting contact piece on one of said ends engageable with the contacts of said first pair to electrically connect the contacts of said first pair in one pivotal position of said carrier and engageable with the contacts of said second pair to electrically connect the contacts of said second pair in another pivotal position of said carrier, and an actuating contour on the other of said ends enabling displacement of said contact carrier between said positions;
• and
• a pair of telescoping guides on opposite sides of said contact carrier, each of said telescoping guides having a respective compression spring and being braced at one end against a respective side of the contact carrier and at an opposite end against said support such that the contact carrier has a snap effect and by application of force to said actuating contour is swingable to jump from one of said positions into the other position corresponding to respective stationary states of said carrier.
