INTRODUCTION circuits with 115 volts of alternating current; 2 amperes This Instruction Sheet (IS) covers the selection and installation of AMP Rotary Programming Switches continuous and up to 125 millamperes during switching. Coded outputs include decimal, binary coded decimal designated as the 3100 Series. See Figure 1. (BCD), and binary coded decimal complement, Read this material thoroughly before starting. Each switch contains a ball and compression spring system that ensures positive positioning and can easily be NOTE Dimensions are in millimeters [with detected upon rotation of the shaft. inches in brackets). The throw of the switch between positions can be 2. DESCRIPTION determined by dividing full rotation (360} by the number of switch positions. Switch positions can be excluded by The switches described on this sheet are designed for limiting shaft rotation using one or both ring/pin stops logic level circuitry, but are capable of controlling electrical supplied with the switch.

All Intemational Rights Reserved. 10F5IS 7936 Switches are supplied as individual units and controlled by a single shaft and detent. Normally the integral pc boards are terminated with commercial interconnect system (CIS) F posts (.558 X .635 [.022 x .025]); however, they can be terminated with AMP pc board edge connectors, pc board receptacles, 180 posted contacts, etc. Consult AMP Engineering for specific details. The switches are designed to be mounted to the back of a panel. The antirotation post helps stabilize and prevent rotation of panel-mounted switches. See Figure 1. 3. INSTALLATION The following procedures apply to switches that have been terminated with F posts (see Figure 1).

A. Switch Selection 1. Determine the number of switch positions and the output code needed for your application. 2. Refer to the chart in Figure 2 and select the switch description that will suit your needs. 3. Referto the chart in Figure 1 for the switch base number and select the applicable switch. B. PC Board Layout 1. Determine the number of switch circuit pads on the switch you are using. 2. Make a layout on your pe board using the di- mensions shown in Figure 2.

Soldering solvents contaminated with dissolved flux, or any Insert the contacts of the switch into your component pc board,then solder (wave or hand solder) and clean the assembly as follows: 1. Wave Solder a. Preheat component pc board. Do NOT allow switch housing temperature to exceed 88C [190 F}. b. Apply flux to bottom of pc board and ends of contacts. Do NOT apply flux to top of pe board. c. With the solder temperature at 260C 500 pass assembly over a 63.5mm 2 1/2 in.) wave of solder. The exposure time UST NOT exceed 5 seconds. 2. Hand Solder a. Obtain a hand soldering iron with a maximum of 37 1/2 watts of power. b. Simultaneously heat the component pc board pad and contact, and apply rosin core solder. 3.

Panel Layout Make a hole layout in the panel using the dimensions shown in Figure 3. Note that the layout shown provides the minimum distance allowed for switches mounted side by side, E. Application of Ring/Pin Stops Two ring/pin stops are supplied attached to each switch shaft in a nonfunctional position. They are used to fimit rotation of the switch shaft to any desired switch position (see Figure 4). If stops are not used, remove them before panel mounting. in Figure 4 the inner circle of numbers represents switch stop positions for CLOCKWISE rotation and the outer circle represents switch stop positions for COUNTERCLOCKWISE rotation. Install ring/pin stops as follows: 1. Remove nut, lockwasher, and stops from threaded shank. 3 OF5IS 7936 3100 SERIES ROTARY SWITCHES 12-POSITION SWITCH 10-POSITION SWITCH 16-POSITION SWITCH 3 5 0 ; 3 23 6%, 22 e39 / 4 24-POSITION .

Determine the position(s) at which the selector is to stop and, using a scribe or other suitable tool, punch hoie(s) in webbing at stop position(s). See Figure 4. NOTE The internal stop is located 180 from the flat on the shaft If stop position is 180 from flat on shaft, rotate shaft one position left or right te permit entry of Stop pin. 4. Install stop(s) as follows: a. One Stop - Align ring/pin stop with shaft so pin is facing switch, then slide ring over threaded shank and insert pin into stop pin hole.

Align the switch with the back of the panel IS 7936 and position the shaft through the shaft hole and anti- rotation post through the post hole. 2, Secure switch to panel with the washer and nut supplied with the switch (maximum torque 15 in.
