GMZ TYPE AUXILIARY SWITCH

GMZ TYPE AUXILIARY SWITCH

FEATURES

High dust-tight structure

High dust-tight structure

High dust-tight structure by rib inside the unit prevents foreign substance invasion.

Wide contact variations

3 kinds of contacts, single silverplating contacts, double bridge silver or gold-plating contacts are available, which meets various requirements.
Wide contact variations

Low energy contact application

Double bridge gold-plating contacts cover low energy application of DC5V, 1mA or more.
Double bridge silver-plating contacts cover DC5V 5mA. (50,000 cycle switching)

High anti-flammability

High anti-flammability

High anti-flammable PBT (Poly-Butylene Terephthalate) plastic is adopted. (class UL94,V-0)

Safety Structure on live portion

Safety Structure on live portion

A terminal cover(Polycarbonate) is equipped as standard equipment for safety improvement.

Combination of different contact units in one switch

Combination of different contact units in one switch

Three different contact units can be assembled in one switch assembly.
* One switch unit can be provided with only one kind contact.

Chattering prevention

Chattering prevention

High-pressure springs on contact portion enhance vibration resistance performance.

Max. 20 unit assembly is available

Max. 20 unit assembly is available

Low twist structure of the switch enables to assemble long switches as many as 20 units (40 contacts). Wide range application such as parallel connection is available.

Max. applicable wire size is 5.5mm2

Applicable wire size is 2 to 5.5 mm2 in spite of its small body.

Rated insulation voltage is 600V

The rated insulation voltage is higher than the previous model. (250V → 600V)

Standard: IEC60947-1,IEC60947-5-1
