602HE5-RB

Snap Action, Limit Switches

602HE5-RB is a kind of snap action, limit switch, popular for its long-term stability, strong anti-interference ability and good sealing performance. It is mainly used for on-off signals in the automation control of electrical appliances, which requires higher mechanical performance, higher temperature resistance and moisture-resistance. Besides, 602HE5-RB is widely applied in smart home, fitness equipment, communication network, textile machinery, medical equipment, etc. 

Working Principle

The working principle of the 602HE5-RB snap action, limit switch is quite simple. In the off-state, the normally open switch contacts are disconnected, and the load current cannot flow. After the switch is operated, it is switched to an on-state, and the normally open/closed contacts are connected, and the load current flows. It is mainly used to detect the power on/off state and break/establish the zero line circuit of the motor in the electrical positioning system.

Features

602HE5-RB snap action, limit switch has many features, such as:

• Small size and compact structure.
• The contacts are made of silver alloy or gold plated, ensuring superior electrical connections and a long service life.
• High temperature resistance of 105℃, high vibration/shake/impact resistance of 10g.
• High temperature test of 250℃ for 2 hours and freezing test at -250℃.
• No extra parts such as button, lever and roller, so the damage chance is lower.
• Good waterproof and dustproof performance.
• Contact form is available in 1a, 1b1, 1c1, and 1d1.
• The ambient temperature can reach between -25℃ to 60℃.
• Certificates such as UL, CE, TUV, Rosh, and ISO9001.

Application Field

602HE5-RB snap action, limit switch is widely applied in many fields such as smart home appliances, machinery manufacturing, electronic products, home and office automation, fitness equipment, petroleum drilling, communication networks, textile machinery, household appliances, medical equipment, etc. It can be used in dimming switch control, ordinary air conditioner, electric heater, lighting control, inverter and other products.

Installation & Maintenance

Before installing the 602HE5-RB snap action, limit switches, please first check and confirm the specification data, installation and wiring diagram. The operator should be familiar with the applicable safety regulations and power frequency. Also, please make sure the parts of the switch are up to the environmental requirements and installed in an appropriate position. 

In terms of maintenance, the regular inspection should be carried out to check whether the output is normal or not. In case of any problems found, please shut down the equipment immediately and confirm the causes. Depending on the situation, the switch needs to be cleaned, adjusted, repaired or replaced.
