When is a switch not a switch?...
The Pseudo-Switch is a fully electronic alternative to mechanical slide and rotary switches. It allows full electronic control, while retaining a simple manual interface with a push button and LEDs to indicate position. Single boards can be joined together to expand the number of switch positions, and the output can be disconnected entirely with activation of the "Inhibit" mode, allowing multiplexing of multiple switches on one signal line. Analogue and digital AC or DC signals can be switched with ease.
The Pseudo-Switch DP4T is equivalent to a double pole, four position, mechanical switch, within the following specifications.
|Supply Voltage||3.0 - 5.5V DC|
|Max. Switch Input Voltage||+5.0V, -4.5V (3V Vcc) I +5.5V, -5.5V (5V Vcc)|
|Max. Switch Current||20mA|
|Switch ON Resistance||<120 - 500 Ohms|
|Switching Time||2 Microseconds|
|Switching Configuration||Break Before Make|
Board Dimensions - Holes suit 3mm or 1/8" bolts.
The range of switch positions can be reduced to two, or three, by use of the pin jumper as indicated by text on the top of the board. Digital control inputs are CMOS compatible and referenced to the external supply voltage.
The Pseudo-Switch DP4T is available with or without the pin headers soldered to the circuit board. Without them soldered to the board, the cost of economy postage is reduced considerably due to the reduced thickness of the package. When soldering the headers, ensure that the "Vcc" pin is soldered directly to the resistor, and jumper wire, next to it on the top of the board.
Postage options marked "(PCB or Kit)" may only be selected if the pin headers are separate, not soldered.
Each order includes a professionally bound 21 page booklet detailing the usage of, and circuitry behind, the Pseudo-Switch. One booklet is included per order regardless of the number of Pseudo-Switches purchased, unless otherwise requested.
Example 1. Basic Usage - In/Out.
Example 2. Basic usage - Microcontroller.
Example 3. Switch Select.
Example 4. Multiplexing.
Example 5. Cascaded poles - 10 position.
The last two positions will take four Clock pulses to advance over. Alternatively, limit the second Pseudo-Switch to two positions for a total of eight.
Example 6. Cascaded poles - 16 position.
Example 7. Input readback.
