Contact Kit

Frequently Asked Questions

Q: What is the TO 0973523 contact kit and what does it contain?
A: The TO 0973523 is a replacement contact kit for Toyota electromagnetic switches and relays. The kit contains spare electrical contacts that wear from repeated switching cycles. Verify the exact number and type of contacts in your kit matches your solenoid or relay specifications.

Q: What voltage and current rating do the TO 0973523 contacts handle?
A: These contacts are rated for 24VDC control circuits used on Toyota lift trucks. Maximum current-carrying capacity depends on contact material and surface area. Do not exceed the original solenoid or relay current rating when using replacement contacts.

Q: Which Toyota switches and relays use the TO 0973523 contact kit?
A: The TO 0973523 is compatible with select Toyota electromagnetic switches and solenoid relays. Confirm your specific switch or relay model number before ordering to ensure the contact kit matches the switch cavity size and terminal configuration.

Q: What are the failure symptoms that indicate contacts need replacement?
A: Worn contacts cause sluggish truck response, intermittent function, or complete circuit loss. Symptoms include delayed motor start, erratic steering response, or flickering indicator lights. Use a multimeter to measure contact resistance, which increases as contacts wear.

Q: How long do replacement contacts last before wearing out again?
A: Replacement contacts typically extend solenoid or relay lifespan by 2 to 4 years under normal warehouse duty. Lifespan depends on switching frequency, load amperage, and electrical cleanliness. High-cycle equipment or systems with voltage spikes degrade contacts faster.
