Prevents inadvertent operation of the switch. Switch can be operated only when the spring-loaded guard is lifted up. Returning guard to the down position forces the switch lever to the off position. Single-hole type for neck-mount switches such as AN3021 and AN3027. Three-hole type for panel-mounted switches such as AN3023. Color: Red.
These are supposed to match with the AN3021, not so much. The guard is too narrow for the toggle so in does not really fit over the handle when closed. Looks very unprofessional.
