Frequently Asked Questions
Q: What are the specifications for Yale micro switch YL 220023939?
A: The YL 220023939 is an OEM Yale micro switch rated 5A resistive load at 250VAC maximum switching voltage. It features silver alloy contacts, quick-connect terminals, glass-filled nylon polymer housing, and 1,000VAC dielectric strength between terminals. Designed for panel-mounted applications in Yale electric lift control circuits.
Q: Which Yale electric lift truck models use the YL 220023939 micro switch?
A: The YL 220023939 is part of the Yale electric lift series control systems. This micro switch is used in safety or functional circuit applications. Confirm your equipment model and control circuit configuration before ordering. Contact us with your equipment model and serial number for correct application verification.
Q: What is the voltage and current rating for the YL 220023939 switch?
A: The YL 220023939 is rated 250VAC maximum switching voltage with a 5A resistive load rating at 250VAC. Dielectric strength is 1,000VAC for one minute between terminals. Do not apply this switch in circuits exceeding these specifications; doing so will damage the switch and create safety hazards.
Q: What type of contacts does the YL 220023939 micro switch have?
A: The YL 220023939 features silver alloy contacts, which provide reliable electrical conductivity and durability in repeated switching applications. Silver alloy contacts resist oxidation and maintain consistent low contact resistance over the 100,000-plus cycle service life.
Q: What is the service life of the YL 220023939 micro switch?
A: The YL 220023939 is rated for over 100,000 mechanical cycles. Actual service life depends on switching frequency and circuit load. Regular inspection of switch operation is recommended. Replace the switch if contacts become pitted, if switching becomes sluggish, or if it fails to engage or disengage within normal operation.
