Bistable Relay/Switch Latching Relay/Impulse Contactors

Available in ratings up to 40 Amp, 1, 2, 3 and 4 Pole Configurations, Bistable relays or Latching(Impulse) Contactors are used for applications where a pulse is given to the Bistable Relay/Contactor which activates the contact. Subsequent Pulses will toggle the ON/Off state of the Relay/Switch. Fastron Electronics distributes Iskra Doo Bistable Relays/Switches and stocks based on market requirements. With over 40 years experience in the power electronics industry, you can sure Fastron can select the correct Bistable Relay/Switch for your requirements. 

For any specification not listed here feel free to contact the friendly team at Fastron Electronics.


FAQ's


1. What is a bistable switch and how does it work?
A bistable switch operates by changing its state with each pulse—one pulse turns it on, the next turns it off—maintaining its position without continuous power.
2. What is the difference between a bistable relay and a latching relay?
There is no major difference; bistable relays and latching relays are often used interchangeably, both changing states with a control pulse.
3. How does a latching relay function in an electrical circuit?
A latching relay receives a pulse to switch on or off and stays in that state until another pulse is received, helping reduce energy usage.
4. Where can I buy high-quality bistable switches in Australia?
You can buy high-quality bistable switches in Australia from Fastron Electronics, which supplies trusted brands like Iskra Doo.
5. What are the advantages of using a latching relay over a standard relay switch?
A latching relay uses less power since it only requires energy during switching, not to maintain its state—unlike a standard relay switch.
6. Can I use a bistable relay in automation systems?
Yes, bistable relays are ideal for automation systems where power efficiency and state retention are important.
7. What are the applications of a bistable switch in industrial settings?
Bistable switches are used in industrial settings for lighting control, energy management, and systems requiring stable on/off states with minimal power use.
8. How do relay switches control power in circuits?
Relay switches control power by opening or closing a circuit when triggered, allowing control of high-voltage loads with low-voltage signals.
9. Are your relay switches suitable for controlling high-voltage devices?
Yes, the relay switches available at Fastron Electronics are suitable for high-voltage applications, with ratings up to 40 amps.
10. Do you offer bistable relays for low-power applications?
Yes, you can find bistable relays at Fastron Electronics that are suitable for low-power or energy-efficient applications.
11. How does a bistable relay help in energy saving?
A bistable relay only consumes power during switching, making it highly energy-efficient compared to relays that need continuous power.
12. Can a latching relay be used for remote control applications?
Yes, a latching relay is ideal for remote control systems, as it maintains its state without needing constant power input.
13. Are your relay switches available with different voltage ratings?
Yes, relay switches at Fastron Electronics are available in various voltage and pole configurations to suit different requirements.
14. How long is the typical lifespan of a bistable relay?
The typical lifespan of a bistable relay is long, especially since it uses less energy and has fewer mechanical movements.
15. Do your bistable switches comply with Australian electrical safety standards?
Yes, bistable switches from Fastron Electronics are sourced from reputable brands and meet Australian safety and quality expectations.
