Specialty Electrical Switches & Relays
How to choose specialty electrical switches & relays
Speciality Electrical Switches include thermal types: NO closes on heat, NC opens, choose by failsafe.
Within Electrical Switches, pick a relay with LED indicator for state view, or a bare PCB relay to save space.
Hardware holds DIP/SIP slide switches: gold plating fights tarnish, standard metal costs less but ages.
Across all sub-types, colour options like red/green or grey help panel coding.
Housing material spans plastic, metal, stainless steel, copper: weight versus durability.
What's good
- Thermal switches (NO or NC) give hands-off temperature cutoff inside enclosures.
- Relay modules with LED indicator show contact state at a glance, speeding fault checks.
- Gold DIP or SIP slide switches hold stable low-voltage signal paths on through-hole boards.
- Single-pole RCBOs pack breaker and earth-fault protection in one narrow unit.
- The broad colour range, from red/green to grey, lets you mark circuits by function.
Things to watch
- Plastic-bodied switches weigh less but wear sooner than metal or stainless steel housings.
- Non-latching miniature PCB relays draw coil current the whole time they stay engaged.
- Gold slide switches suit signal-level currents, not mains amperage.
- Fixed-temperature thermal switches (15°C or 80°C types) cannot be recalibrated in field.
- Relay modules with LED take more panel room than bare relay versions.
Care & maintenance
Wipe metal or stainless fronts with a dry cloth to keep corrosion at bay.
Test thermal switches at their rated trip point during annual panel checks.
Confirm the LED on relay modules matches the actual contact state when inspecting.
Slide gold DIP switches only when needed, as excess movement thins the plating.
