What do the part numbers mean?
Part numbers for components can often be confusing, so we’ve provided this handy guide to break down what each part of the number means, plus some examples of what these parts look like.
For Indicators or Push Button Switches:
As an example, if you ordered an RJS-PS8A-381-RE, the switch pictured here is what you would receive. A red, square LED illuminated push button switch, with an 8mm panel cut out. It would have a latching function, SPDT (single pole, double throw) contact and 12 volts direct current.
For Key Lock or Selector Switches:
As an example, if you ordered an RJS-PS16A-732-3, you would receive the switch pictured here. A non-illuminated, rectangular key lock switch, with a 16mm panel cut out. It would have a 3 position configuration with a latching function, and DPDT (double pole, double throw) contact.
