Electrical rated parameters of vacuum pressure switches

The electrical rated parameters of vacuum pressure switches mainly include rated voltage, rated current, output signal type and power, etc.

In terms of rated voltage, some vacuum pressure switches have a relatively wide rated voltage range, such as DC4.5-28V. There are also models that are compatible with both AC and DC, such as AC/DC100V and below.

In terms of rated current, the maximum operating current range varies among different models of switches. For instance, some models have a maximum operating current of 50mA below 24V, 40mA at 48V, and 20mA at 100V.

The output signal types are diverse. Common ones include single-pole double-throw (SPDT) output, as well as types such as quick-acting microswitches, normally open (NO), and normally closed (NC) contacts.

In terms of power, the contact capacity of some models is AC2VA and DC2W.
