This Switch adopt PZ-215 type mercury switch, With epoxy resin fixed outside the polyethylene In the shell, will lead to one of the cable end, At the same time become fully enclosed switch. Acid and alkali plant in chemical plant and mine in the high humidity areas has very good waterproof anti-corrosion Ability.
This switch is referring to the similar products of foreign mining winch the security switch, its structure is Simple,low cost, can be directly fixed on the mechanical transmission parts, are widely used in Signal or positioning control.
According to the switch work position with mounting holes use screws to fix the switch, The switch should be with a 5 mm thick layer of rubber piece when it should have been to be fixed. Set screw shoulds not be too tight, in order to avoid cracked epoxy resin. The switch should to connect large angle to a direction before electricity, the mercury is full of water Silver electrode of the switch. In order to avoid the electrode in large electrical flow has Direct contact with mercury Spark, and ablation electrode increased by oxidation of electrode contact resistance.
