Frequently Asked Questions
Q: What is the difference between the self-locking and self-resetting modes on this mushroom head switch?
A: In self-locking (latching) mode, the button stays depressed after you push it and must be released by pulling or twisting it back out — ideal for maintaining a stopped state until deliberately reset. In self-resetting (spring-return momentary) mode, the button automatically returns to its original position as soon as pressure is released — best for buzzers or pulse-type commands.
Q: Is this emergency stop button switch suitable for outdoor or washdown environments?
A: Yes. The IP65 rating means the housing is fully dust-tight and protected against direct high-pressure water jets, making it suitable for outdoor industrial installations, food processing lines, and other washdown environments.
Q: Can I add more contact blocks to this switch for NC (Normally Closed) configurations?
A: Absolutely. The modular snap-in contact block design allows you to add or swap compatible NC or NO contact blocks to suit your specific wiring requirements. The set includes one 1NO contact block, and additional blocks can be purchased separately.
Q: What cable entry options does this switch support?
A: The enclosure supports up to three M20 (PG13.5) cable glands or one M16 cable gland, giving you flexible options for clean and secure cable routing in your installation.
