| 摘要 | The switching part (1) of the inventive switch is tightly enclosed by an elastic membrane (5) in at least the area of its free end. Said membrane also envelopes the contact surfaces (2) which face towards the switching part (1), at a distance, and is tightly connected to the switch housing (4; 6). This ensures that the contact area is tightly sealed in relation to the environment of the switch, which in turn ensures reliable protection against contamination and oxidation of the contact surfaces. The number of switch components is reduced, advantageously, an additional mechanical spring for holding the latching position of the switching part (1) being superfluous, and miniature embodiments are therefore also possible. | ||||||
