した大規模格子状スイッチを提供することにある。However, in such conventional large-scale grid-like switches, as the scale of the switch increases, the number of contacts connected to one circuit increases, and the circuit length also increases, resulting in crosstalk. It also had the disadvantage of having a large negative impact on reflection characteristics. SUMMARY OF THE INVENTION An object of the present invention is to provide a large-scale grid switch with improved crosstalk and reflection characteristics by reducing the number of contacts and shortening the circuit length, in order to eliminate the above-mentioned conventional drawbacks.

130 input terminals al゛a3, b1-b3, C1-C3
are connected one-to-one to the output terminals of the selective switches Sil, Si2, and Si3, respectively, and the input terminals 110, 120, and 130 are connected to the plurality of output terminals of the selective switches Sil, Si2, and Si3, respectively. The input terminals of the lattice type switches 5M210 to 5M330 are also connected to the selection type switch, although illustration is similarly omitted below. In addition, lattice switch SM710~5
Output terminals pl, p2...pn of M330 (not shown)
are selection type switches 501, 502... So
Output terminals 010, 020, etc. of n (not shown)
- Connected one-to-one to on0 (not shown). In this case, the input terminal 110 of the selective switch SiljSi25Si3 and the output terminal can be connected, and the input terminals a1-A3, bl-B3, cl-E3 of the grid-shaped switch SMllO-SM33O and the output terminal P,・P2...Pn can be connected, and the selection type switch SOlwoSO2llSOn
The output terminals 0105020j11...0n0 also have the function of input terminals. In addition to the large-scale lattice type switch having the above configuration, the input terminal 12 of the selection type switch Si2
0 and selection type switch S. The circuit from the output terminal 120 of , to the output terminal 010 of the selective switch SO1 includes a selective switch Si2, a lattice switch SMllO, and a selective switch S. , consists of three switches. Therefore, the input terminal 12 of the selective switch Si2
Selection type switch S from 0. The crosstalk and reflection characteristics of the circuit up to the output terminal 010 of l are determined by the selective switch Si2,
Lattice type switch SMl, O and selection type switch S. l
Since it is determined only by In addition, the lattice switch SMllO is
Since it is not directly connected to other grid switches, the number of contacts is reduced, which reduces crosstalk and adverse effects on reflection characteristics. In addition, in the above description, the selection type switch SiP input terminal 120 and the selection type switch S.
Although the case has been described in which the output terminals of the selection switches 1 and 1 are connected, if the input/output terminals of other selection switches are connected, the same configuration and function as described above will be obtained. As explained above, the present invention consists of one circuit consisting of three input/output side selection type switches and a grid type switch, and by configuring the grid type switches so that there is no direct connection between them. This has the effect of reducing crosstalk and deterioration of reflection characteristics due to an increase in switch scale.
