I need a 12v switch to respond to a 433.92 Mhz signal

AI Thread Summary
A user seeks a 12V switch that responds to a 433.92 MHz signal for an actuator, emphasizing the need for a simple schematic or source. The discussion highlights the importance of understanding the RF signal's source, modulation, and expected signal strength for effective assistance. The specific model mentioned is the WS4916 from DSC, but compatibility with available receivers like the DSC RXL2-433 is uncertain. The community suggests contacting DSC for clarification on compatibility and encourages the user to provide more context about their project for better recommendations. Clear communication about the project's goals is essential for finding a suitable solution.

Im not an elctrical engineer but I do need a source for the above mentioned switch. I would even be open to a simple schematic. Please Help.

Welcome to the PF.

What is the source of that signal? How is it being modulated? What receive signal level do you expect from a resonant antenna at your receiver?
 
This is a simple 12v dc current that I need to interrupt in the form of a RF receiver switch that simply will close up receiving the radio signal thus allowing the voltage to pass to the accuator

Sure. But you need to answer the questions I asked, in order for us to help you. We need to know a lot more about the RF signal (its source, strength, modulation, etc.).
 
I can't seem to get that technical data all I can provide is the model and serial number of the source and hope you can find the specific info you need. WS4916 - DSC Wireless Heat & Smoke Detector
 
For this sort of thing, you'd almost certainly need a receiver from the same company (unless you disassembled one and discovered that the wireless module is just a COTS type module that you can purchase elsewhere).

Unfortunately, the DSC RXL2-433 wireless receiver relay driver doesn't list the fire alarm as a compatible device (though it might still work, even if it's not intended for the application--I'd contact DSC to see if they'd know). Using the DSC RF5108-433 receiver module doesn't output to a user form either (it's for integration into the DSC panel).

Maybe if you backed up a bit and told us what you're trying to accomplish, we can recommend an alternative?
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
